When testing electric pumps and their controllers, what shall the inspector do first?

Explanation:
Identifying all sources of electrical supply feeding the pump and its controller must come first. Knowing every possible source lets you plan complete isolation and de-energization, so no hidden feed can energize parts during testing. After identifying the sources, you would apply lockout/tagout and verify zero energy before proceeding. Opening the controller cabinet or starting the pump without establishing isolation exposes you to live voltages or unexpected motion, which is unsafe.
